ATEN'T DEVICE FOR TIGHTENING LOOSE SPINDLESL' SPECIFICATION forming part of Letters Patent No. 532,1 90, dated January 8, 1895. Application filed October 4, 39:4; Serial No. 524,904. (No model.)

To all whom, it; may concern:

Be it'known that I, PIUS S. SNYDER, a citi zen of the United States, residing at Jacobus, in the county of York and State of Pennsylvania, have invented certain new and useful Improvements in Devices for Tightening Loose Spindles; and I do'hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

My invention consists in a novel and valuable device for tightening loose spindles, which will be hereinafter fully described and claimed, and its advantages pointed out in .detail.

Referring to the accompanying drawings, in which the same letters of reference indicate corresponding parts in the several figures: Figure 1 is a perspective view illustrating my invention. Fig. 2 is a perspective detail View taken with the top block of the device removed. Fig. 3 is a sectional view taken on the plane indicated by line cc-.r, Fig. 4; the blocks A and L and base-piece B being shown in section. Fig. 4; is a sectional view taken at right angles to Fig. 3, on line yy, Fig. 3; the blocks A and L, the base B, the inner ends of the levers G, and the bands P being shown in section. Fig. 5 is a section of an axle-box showing a spindle therein after it has been adjusted by my device. Fig 6 is a top plan view of the block A.

All persons accustomed to the use of vehicles are aware that when the spindles wear loose the only remedy at present is to remove the axle with its worn spindles and replace it by a new one. By my invention, however, the worn spindle can be adjusted, as hereinafter described to fit practically like new for one-fifth what a-new axle would cost, while the spindle thus treated will'wear as long as it did in the first place, will hold the grease better, and will cause the wheels and buggy to run easier and with less friction, as hereinafter described. The worn spindle is treated or adjusted without removing the axle from the buggy, and without injuring the paint or circle.

varnished surfaceand the spindle is not heated, which injures its temper.

Referring to the several parts of my device in detail, A indicates the body block of the device, this metal block being secured on a base-piece, B, which may be integral with the block, as shown in Figs. 3 and 4, so that its ends are slightly raised, to receive the metal retaining hoops. The base is preferably bolted upon a bench, X, having the legs Y; but it is obvious that it may be mounted in any suitable or desired manner. Upon the top of the metal block A is formed, longitudinally, the curved recess or seat 0 adapted to receive the spindle of an axle; and in the center of the block are formed the deep lever recesses, D, D, arranged side by side and opening one through each side'of the block, as shown. At the center of each of said recesses is formed the curved depression or pivotal seat E, while from said depression, at

the innerend of the recess, rises the curved,

bearing surface F, curved in the arc of a The two curved bearing surfaces F, curvingin opposite directions, are so arranged and formed that their lower ends are on the same central line, as shown. Y

The two pressure levers, G, G, which form part of the device are formed each at its inner end with the lower curved extension H which fits in the curved seat E, the curved end-face block A, the top block L is placed in position, this block having formed in its lower side the longitudinal spindle recess M, at the central part of which is formed the curved depression 'N,whioh permits of the spindle being bent npat that point by the pressure of the levers.

In order to regulate the exact extent to which each spindle will be bent up, as required by the extent to which it has been worn, the adjusting screw 0 is mounted vertically in the top block at the center of the depression N.

Before placing the top block on the operator measures the exact height to which theworn spindle should be bent up by the levers in oriii?- der to make it fit tight in the axle box at that point, and then turns the adjusting screw 0 to the required point. The top block is then firmly secured on the block A by slipping over the ends of the two blocks the metal retaining loops P, P, and turning down the binding screws Q which work through the top of said loops near their upper corners. Instead of these screws wedges may be employed, which can be pressed under the upper ends of said loops to tighten them. It will now be seen, the worn spindle being thus secured in position, that, when the extended outer ends of the pressure levers are pressed down, the curved upper pressure surfaces F at the inner ends of said levers will press up against the spindle at its center, slowly but with great power, owing to the formation of the inner ends of the levers and the seats in which they are mounted, thus bending up the center of the spindle to the desired extent, which is regulated by its coming in contact with the inner end of the adjusting screw 0. When the wheel is replaced on the previously loose spindle, thus bent, the upwardly-bent center of the spindle will contact on its upper side with the interior of the axle-box, as shown in Fig. 5, and will also touch the box on its lower side at. each end; this slight sharp upward as it did when new.

The great practical convenience and advantages of my invention will be readily understood. It will be seen that it is simple in construction; that it can be used by any blacksmith or owner of a vehicle; that a spindle when worn loose can be quickly, without heating it or removing the axle from the vehicle, be thus bent or adjusted to fit practically as tight as when new, for one-fifth of what a new axle would cost; and will wear as long as it did in the first place. I have found that the Wheels, and the buggy, when the spindles are thus treated, will run much easier, with far less friction; also, the spindle where bent up at its center will form a space or pocket, see Fig. 5, which will hold the grease, so that the spindle will remain well greased longer than with a new spindle where its entire surface is exposed to friction. As before stated, the spindles are adjusted without taking the axle from the vehicle; and without injuring the paint or varnished surface.

Having thus described my invention, what I claim, and desire to secure by Letters Patcut, is

1. A device for tightening loose spindles 2. The combination of a body-block formed with the top longitudinal spindle recess and the central transverse lever recesses and seats, a recessed top block and means for securing the same on the body block, and the pressure levers formed at their inner ends.

with the bearing heads having the curved upper pressure faces K; substantially as set forth.

3. The combination of a body block formed with the top spindle recess, the transverse lever recesses extending in side by side from opposite sides of the block, and the central curved seats, the top block having the spindle recess in its lower face with the depression at the center thereof, means for securing said block in position, and the pressure 1evers formed at their inner ends with the lower bearing projections H and the curved upper pressure faces K, substantially as and for the purposes set forth.

4. The combination of a body block formed with the top spindle recess, the transverse lever recesses extending side by side from opposite sides of the block, and the central curved seats the top block having the spindle recess in its lower face with the depression at the center thereof, and having the central adjusting screw, means for securing said block in position, and the pressure levers formed at their inner ends with the lower bearing projection H and the curved upper pressure faces K; substantially as set forth.

5. The combination of the suitably supported block A formed with the top spindle recess, the transverse lever recesses extending side by side from opposite sides of the block, the central seats E, and the curved bearing surfaces F, the top block having the spindle recess in its lower face with the depression at the center thereof, and having the central adjusting screw, means .for securing said block in position, and the pressure levers formed at their inner ends with the lower curved extensions H, the curved end faces I, and the curved upper pressure faces K; substantially as set forth.

In testimony whereof I affix my signature in presence of two witnesses.

-PIUS S. SNYDER.
